Arsene Wenger says he backs VAR, but there must be changes to how the technology is used after Liverpool's clash against Manchester City.
Jurgen Klopp's side beat Manchester City 3-1 at Anfield to move nine points clear of Pep Guardiola's side at the top of the Premier League table, with goals from Fabinho, Mohamed Salah and Sadio Mane enough to seal three points.
But Salah's goal in the first half sparked controversy after being sent for a VAR check for offside.
The Reds forward nodded past Claudio Bravo after getting on the end of a cross from Andrew Robertson.
But a replay appeared to show that the Egpytian may have been marginally offside as the ball was played into the box.
VAR checked Salah's goal against City at the Stockley Park HQ, and the PGMOL released a brief statement that said: "VAR checked for possible offside, and confirmed that the Salah goal was correct."
Speaking as a pundit for beIN Sports, former Arsenal head coach Wenger says he supports the concept of VAR but feels the technology is the issue.
"It [VAR] is working but it is not working on all occasions. It's better than before, you have more right decisions especially on offsides for example.
"You have to make a rule, the only uncertainty about offside is the timing when you stop [to check]. It has to be super accurate, it has to be right.
"If you have a player, a quick player, and he makes approximately nine centimetres in 0.08 seconds that's a big distance. That's why the moment when you block the image it's absolutely vital especially if you have 25 pictures per second.
"I'm delivering a message, at the moment it's [VAR] manual with the help of what they call the key eyes, but I think it has to be completely automatic."
